Kara's not entirely sure what comes over her, not entirely sure of anything but how beautiful Lena is today—how cozy and warm and soft and devastatingly sexy she looks—and all she's doing is just sitting at the table in a ribbed, black turtleneck and black jeans, with her flawless brows and plum-dark lip, and her wavy hair up in a bun that's somehow managing to exist in the limbo between neat and messy, her little flyaway hairs just begging for Kara to curl her fingers in.
No, Kara's not entirely sure what comes over her, but as has become increasingly common lately, finds herself alone with Lena while she's looking this lovely, and she just can't stop staring and wondering—
"Can I kiss your stomach?" she asks.
Lena's perfect eyebrows lift in surprise, but she calmly sets her mug of hot tea down.
"Excuse me?" she says, like she just wants to clarify that Kara's indeed lost all of her marbles, and maybe some of someone else’s too.
"Uh, I mean," Kara flounders, blinking quickly and waving her hands wildly like the next words out of her mouth are an explanation and not, once again, "Can I kiss your stomach?"
Lena's face is unreadable as she levels Kara with a look and folds her arms on the table.
"Whatever could've possessed you to want to do that, Kara?" she asks, like she isn't the most beautiful woman Kara's ever seen.
"You're the most beautiful woman I've ever seen," Kara says earnestly. "And also you look so soft and warm in that sweater, which just got me thinking about how soft and warm your skin probably is underneath. And that got me thinking about feeling how soft and warm you are, uh, with my mouth, but it felt too awkward to ask to kiss your neck 'cause that's a little inappropriate, and I can't kiss your shoulders ‘cause that involves stretching your sweater too much or taking it off—which is also inappropriate—so… stomach is what I came up with."
"Uhuh," says Lena, looking incredibly unimpressed.
"'Cause you can just… lift your sweater up a little," Kara explains weakly, miming the motion.
"Right, I got that," Lena says, because of course she did. She's a world-saving genius.
"Right," Kara echoes, pressing her lips together and fighting the urge to fidget.
Lena doesn't say anything more, just sits there tapping the fingers of one hand against the elbow of the other, and Kara considers flying around the planet a couple hundred times to cool the embarrassed flush burning the tips of her ears.
Right around the time Kara decides she might need to go for a dip in the arctic too for good measure, Lena abruptly says, "Sure, why not."
"What?" Kara asks over her shoulder, one leg comically dangling where it's hooked over the balcony railing.
Lena smiles at her. "I said, 'Sure, why not.'"
Kara hops unsteadily, cape swishing and twisting around her one grounded leg as she awkwardly hauls her other leg back over the railing, then dashes back to stand in front of Lena.
"Really?" she asks, incredulous.
"Mmhm, why not," Lena repeats with a light shrug. She curls her fingers under the hem of her sweater and Kara's eyes immediately follow. "So…"
"Um! Yes!" Kara says unnecessarily, and loudly, too loud, as she drops to her knees in front of the low stool Lena's perched on. Lena doesn't immediately lift her top up but Kara keeps staring, unblinking, afraid to miss anything.
"Everything okay?" Lena asks, and Kara could kiss her best friend for checking in right now, moments away from pulling her sweater up to let Kara put her mouth on her stomach.
"Absolutely, a hundred percent," Kara says, tearing her eyes away for just a second to meet Lena's gaze and smile reassuringly. "So okay."
"Okay," Lena says, fingers going white-knuckled as she starts to—
"Are you okay?" Kara blurts, looking up at her again because it's important. It's so, so important that Lena be okay with. Whatever the fuck this is.
There's a delicate rosiness to her cheeks that Kara hadn't noticed before.
"Yeah, of course!" Lena says emphatically, which is at odds with the way she nervously licks out at her lower lip. Kara is utterly enthralled by the damp it leaves behind. "It's just a little embarrassing, is all."
"Oh shoot! I'm so sorry, we don't have to do this!" Kara says, preparing to get up and pretend like this never happened.
"No, I mean," Lena lowers the sweater hem back to her lap and Kara pauses. "I mean, Kara, you're Supergirl. Powered by the sun. Practically a god, and built like one too. And I'm a very human woman."
Understanding dawns on Kara and she lifts both hands to squeeze comfortingly at Lena's thighs, opting to leave them there afterwards as she leans in confidentially.
"Lena, I know for a fact that you work out more than me and eat healthier," she says. "Honestly? They should've gotten you to do the healthy eating PSA instead."
Lena snorts and Kara grins, pressing on.
"But even if you didn't, I'd think you were gorgeous. You are gorgeous, Lena, and I'd really like to put my mouth on you if that's okay with you."
Lena's breath catches and her cheeks are even rosier, but she seems less anxious than she'd been before.
"I'd like that," she says softly, fiddling with her sweater hem.
"Me too," Kara says, eyes once more glued to Lena's fingers. "Very much."
Lena slowly lifts her sweater up then and Kara feels her pounding heartbeat match every aching millimeter of revealed skin.
"Oh wow," Kara breathes, helplessly scooting closer to squeeze between Lena's legs, hands sliding up her thighs and around to press at the skin of her lower back. "Wow, you're even prettier than I imagined. And so soft. And warm."
Lena squirms slightly, voice airy when she says, "You're warm too. Your hands."
Kara curls her fingers to scratch lightly at Lena's back, something gooey settling in her belly when a tiny noise catches in Lena's throat as her back arches.
"Can I kiss you now?" she asks, voice low.
"Yeah," Lena whispers.
Kara leans in and indulgently nuzzles at a smattering of freckles she spots on the skin of Lena's stomach, breathing in the sweet, clean smell she recognizes as Lena's natural scent.
"Y'smell good," she mumbles, lips tickling where they brush against soft belly.
Lena makes another little sound, thighs squeezing around Kara's shoulders, and the gooey something in her stomach grows warm.
Kara kisses Lena's belly properly, once over a freckle, then once again, then twice, hands keeping her close as her kisses meander left and right, up and down. And down. And—
Lena's breath keeps hitching, heart beating drumline loud in Kara's ears, or maybe it's her own heart.
"Doing okay?" she asks, mouth still smooshed to soft skin.
"Mmhm," Lena hums, pitch high and tilting higher when Kara mouths another kiss right over the waistband of her mid-rise jeans.
Kara brings her hands back around and slips her thumbs just under the waistband, stifling the desire to moan when Lena trembles. She tugs ever-so-slightly downward, revealing lovely skin reddened and creased by the press of denim. She coos sympathetically and dips forward, moving her lips softly over the unhappy lines like the gentle press of her mouth could possibly erase hours of being squeezed by jeans.
"Doesn't hurt?" she asks, thumbs brushing over the creases across Lena's stomach
"No, you're very gentle," Lena reassures her, releasing her sweater with one hand to scratch her scalp.
Kara's eyes slip closed involuntarily and she hums.
"Mm, good, that's really nice," she mumbles about the blunt nails working through her hair, feeling warm and happy from that and the affirmation. "But I meant the lines from the jeans."
The fingers still and Kara nuzzles at Lena's belly with an entreating noise, hoping to encourage her to keep going. Luckily, she does, and Kara sighs contentedly, moving her lips against Lena's stomach again and enjoying the light drag of skin on skin.
"Um, no, those don't hurt," Lena says as she runs her fingers through Kara's hair.
"'Kay, good," says Kara. "just checking."
She slides her left hand over to thumb at the button of Lena's jeans as she presses increasingly wet kisses along the revealed skin just under the waistband.
It almost seems like Lena lifts her hips up into her mouth and hands, and god, she wants—
"Can I…?" Kara asks, tapping the button.
"Yeah," Lena says, more breath than sound.
Kara likes the way her voice sounds like that. She unbuttons Lena's jeans, then eases the zipper down and peels the denim away, freeing more pretty skin and a hint of black lace.
"Wow," she says again, because the first two times weren't enough.
And then because there are no more words that could suffice, she leans in and drags her tongue over Lena's hipbone, just above the lace.
Lena whimpers, fingers tightening in Kara's hair, and Kara freezes with her tongue halfway out. She cautiously scrapes her teeth lightly over the bone and is rewarded with a shuddery gasp and a tug to the back of her head. Both excellent reactions.
She has to experiment then, alternating between kisses and licks and little nips and scrapes of her teeth, moving up until her head is bumping into the hand Lena is using to hold her sweater out of the way and kissing back down in a curve following her ribcage, first left then right, lingering every time she meets a freckle and every time a spot makes Lena squirm on the stool or squeeze her thighs inwards.
In this manner, Kara eventually maps all of Lena's soft belly, knows that scraping her teeth against a rib on her left side makes her hiss and pull at Kara's hair; knows that slow kisses up and down the middle of her tummy makes her breathe deep and rub Kara's scalp; knows that the wetter she makes her kisses below belly button level, the more she whimpers and rolls her hips up and clutches at Kara's head.
It's one of these times, while Kara is swirling her tongue somewhere between her belly button and the tantalizing lace of her underwear, that Lena curls forward with a breathy moan and weakly pushes Kara away.
"Okay," she says, voice scratchy. "Okay, I can't take anymore."
Kara whines unhappily, pout pulling the corners of her mouth down and scrunching her brows, but stops immediately.
“What’s wrong?” she asks, worried.
Lena drops her sweater and covers her face with both hands.
“Lena?” Kara asks, carefully wrapping her fingers around her wrists and trying not to let too much panic bleed into her voice. “Are you okay? Did I hurt you?”
Lena sucks in a shaky breath, wetting her lips.
“I’m okay,” she mumbles from behind her hands. “You didn’t hurt me. It just—” She pauses and breathes out slowly, finishing in a near-whisper. “It was just starting to feel too good.”
“Oh,” Kara says, blinking. She strokes her thumbs against her wrists, feeling the strong pulse hammering just under the thin skin. "It felt good?"
"Yeah," Lena says, and when she lets Kara gently pull her hands away, she's blushing prettily.
"It felt good for me too," Kara admits shyly, rubbing her cheek against the back of Lena's hand, heart swelling to the size of a blue whale, or something else equally big and maybe not as blue.
"Oh, okay, good," Lena says, smiling wide and dimply. She brushes her knuckles tenderly across Kara's cheek.
"I really like how it feels to have my mouth on you," Kara says.
Lena shivers slightly, the corner of her mouth quirking up.
"I… really like it too. Maybe we can do it again sometime?"
"But not now?" Kara asks, more than a little disappointed.
Lena nibbles at her lip and Kara spares a moment to marvel at the way her lipstick has held so perfectly before her focus is drawn to the motion of her reaching for her sweater again.
"I guess..." Lena starts, lifting her top up. "I guess a little more now couldn't hurt…"
Kara grins and leans in.
"Do you think it's safe to go back in yet?" Nia asks, leaning with one foot against the wall.
Brainy presses his ear to the door, listens for a beat, then shakes his head with a shrug.
"Unclear," he says, before mirroring her on the other side of the door.
"Maybe it's better to just wait for them to come out…"
